Alexandra Fitzsimmons

Founder & Patron

Alexandra studied maths at the University of Cambridge. She then spent almost a decade working in museums and creative media – for example, working directly with visitors on family activities at the V&A, and as an international exhibition design consultant. Shocked by the lack of fun family experiences available in maths, she founded Maths on Toast. Alexandra is a Fellow of the School for Social Entrepreneurs and spent many years teaching Museum Studies as part of the MSc Science Communication at Imperial College London.

Karrie Liu


Karrie is a mathematician (specialising in data science) with 10+ years of experience in UK healthcare and life sciences; she set up Hypatia Analytics in 2019, in the hope of getting the balance between working as an independent data scientist, incorporate assignments and spending time on pro bono projects and charities. She believes data and mathematics are at the heart of better decision-making and is important to apply these insights to planning. Karrie wants to help everyone share her love of maths!
